Actually I have discovered what may be a solution. It seems the latest nvidia drivers don't play nicely with older versions of the kernel (i.e. 2.6.9). For now, it seems to run ok when I put noapic in the kernel options in grub.conf. Let me know how it goes for you.

I had run the bug report just before my old MX440 video card died, and I had to replace it. I bought a geforce4 FX5200.

I dropped in the FX5200 and switched XORG.CONF to use the previously compiled 'nvidia' driver from the MX440 instead of the SUSE 'nv' driver. It ran, but GL wasn't working. I assumed that my old dying video card was the overall problem, and left it at that. But I was still under the MX440 drivers. It ran fine for a week or two, and I decided to get it running the proper drivers for the FX5200.

So last night I re-compiled the latest drivers (8762) and installed them for the FX5200.

I am now once again seeing the same X freezes as before.

I ran the bug report again yesterday before running X and I have attached it also.

Have you verified that you're using the latest BIOS?
Does this problem persist with a more recent kernel (2.6.17.x)?
If you boot with the noapic and/or acpi=off kernel parameters, does that have any impact?
